PURPOSE:To maintain a load of a non-utility generator substantially constant by controlling to alter the ratio of the outputs of power rectifiers of both CVCF inverters connected to a commercial power source and the non-utility generation power source irrespective of the load standing of power inversion. CONSTITUTION:A power regulator 5 calculates to control so that a deviation between a power set value from a setter 2 given through an adder/subtractor 3 and a power amount detection value from a detector 4 should become '0'. when the output of the regulator 5 is a certain positive or negative value, the power rectifiers 61 of inverters 6A, 6B are controlled in response to the value, but when a command of output increase (decrease) is output to the power reac tor of the inverter 6A side, a complementary operation is so conducted as to apply a command of output decrease (increase) to the power reactor of the inverter 6B side. Thus, a non-utility generation is controlled constantly by altering the sharing ratio of the rectifiers 61. |
